That thing where you put on a fresh pair of socks and one has a hole so you think well I went to all that trouble to pull it on, this will be your last day little buddy, I’ll just throw it away after I wear it today.
Last chance underwear happen now and again as well but I guess it depends on where the hole is.
For some reason I thought that modern machine-made socks couldn’t be darned. Maybe because my understanding is that other modern clothes like pants that rip next to a seam can’t be reliably repaired? (Like, the seam holds but the fabric itself rips)
